The above map of from Eric Schewe's blog, which has some great analysis of the presidential election and much else. It's a great blog for Egypt nerds. He writes of the map and the data behind it:

The fact that the Muslim Brotherhood count from June 18 and the official state count were so close gives me confidence that, while votes may have been illegitimately influenced by actions outside the polling booth, that the polls themselves were relatively fairly conducted. This means this body of data is the first reliable indication ever of Egyptians’ preferences over a very stark binary choice for the direction of the state: Islamism or “Feloul” (old-regime) revanchism. Obviously, many Egyptians went out to vote AGAINST either choice, but the geographical distribution of the result shows very strong regional tendencies, raising interesting questions about voters’ overall motives.

Getting this kind of data and spreading will lead, over time, in a quantum leap in how we understand Egyptian politics. Of course it needs to be combined with new data added over time and knowledge of local-level dynamics. But at long last, we have a base based on an electoral process that was reasonably free and fair.
